Question: How to factor $x^{2} + b x \pm c$ without quadratic formulas (b,c are integers)

Answer: A trick to factor such equations is that we find two factors of c such they add up to b (if + sign) or subtract to b(if - sign) e.g factor $x^{2} + 5 x - 6$ . Now 6 has two factors: 6 and 1 which subtract to 5. so using this trick, we can write $x^{2} + 6 x - x - 6$ , which gives $(x + 6) (x - 1)$
